ATTACHMENT FOR SEWING-MACHINE TREADLES.-

SPECIFICATION forming part of Letters Patent No. 236,706, dated January 18, 1881.

Application filed November 13, 1880. (N 0 model.)

To all whom it may concern.-

Beit known thatI, LEVIN T. JONES, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Attachments for Sewing-Machine Treadles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon ,which form a part of this specification.

My invention relates to an improved attachment designed particularlyfor sewing-machine treadles, and has for its object to provide for running the machine bya hand-operated device whose handle may be in convenient position on either side of the person, as desired, so as to be grasped by either hand.

The attachment will first be described, and the invention will then be designated in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a machine in which a portion of one side of the legs are broken away to plainly show the treadle. Fig. 2 is a plan view of the treadle with the attachment. Fig. 3 is a plan view, showing a modification. Figs. 4, 5, and 6 are detail views, on a large scale, of the handle-rod.

The letter A designates the pedals of an ordinary treadle. A rod, B, has secured to it, midway of-its ends, a clamp, 0, provided with set-screws d, by which the rod is attached to the heel end or front of the pedal, and at the central part thereof, and extends crosswise, one end projecting laterally from each side of the pedal. At each end of this rod another rod, B, is secured so as to project therefrom at a right angle and in a direction forward from the pedal, and at the end of each rod B is a T-shaped metalfplate, E. A pin, f, projects from the plate and serves as a pivot for the connection of the handle-rod G, the lower end of which is provided with an inverted L-shaped or right-angled connecting-block, H, to which the handle-rod G is attached. One part of this block has an eye or hole, It, adapted to slip onto the pin f. When the handle-rod is thus pivoted the right-angled offset n of the block H is raised above the upper surface of the T-shaped plate E sufficiently to permit of a moderate lateral movement of the upper end of the handle-rod on its pivot; but the offset a limits the movement of the handle-rod, by acting as a stop, when it comes in contact with the upper surface of the plate E, and serves to keep the handle-rod in an upright position. The upper end of the handle-rod is provided with a suitable hand-grasp, 1).

By a modification in the construction the rod B may be dispensed with. In such case it would be necessary to make the pedals fast to the usual rod :0, on which they pivot, thus making said rod a rock-shaft, and then secure to the rock-shaft, on each side of the pedal, a rod, B, to project forward, as shown in Fig. 3. By this arrangement of a handle-rod projecting up at the side of the person, it is in a convenient position to be grasped by the hand, and may be easily operated up and down; and, being pivoted at its lower end, afiords to the hand of the opera tor a free lateral movement toward and from the machine unlike that of a horizontal lever.

As the handle-rod is detachable by simply slipping it 0E the pin, the one handle may be connected upon either side of the machine, as desired, so as to be used by either hand, or it may be removed entirely when operating the treadle by the feet. My attachment differs from anything of which I have knowledge, in several respects, one being in the matter of the rod attached by its central part directly to the front of the pedal, so that an end of the rod will project from each of the two opposite sides of the pedal.

The particular manner of attaching the device to the treadleto wit, by clamping it to the heel or front of the pedal and at the latters central partadmits of the two feet being placed on the pedal, the same as if the device were not attached. The device, when thus placed, serves as a counterpoise to the longer or toe end of the pedal and pitman.

Having described my invention, I claim and desire to secure by Letters Patent of the tending crosswise thereof, so that the two ends of the rod will project from opposite sides of the pedal, and a handle-rod connected to the end of the cross-rod, substantially as set forth.

5 2. In combination with the pedals of a treadle, a rod, B, on each side of the pedals, each projecting forward at an angle to the pivoting-rod of the pedal, and a handle-rod, G, connected to the rod first mentioned and pro- 10 jeeting upward, substantially as set forth.

3. An attachment for sewing-machine treadles, consisting of a cross-rod, B, provided intermediate of its ends with a clamp, a rod,
